Aromatic azomethines are prepared by reacting anilines with formaldehyde and then removing the greater part of the water by distillation, low-boiling alcohols, in certain amounts, being present during the distillation and, if desired, during the reaction or during a part thereof. The aromatic azomethines obtainable by the novel process are valuable starting materials for the preparation of herbicides, especially pre-emergence herbicides and post-emergence herbicides, fungicides, insecticides, bacteriostatic agents, fungistatic agents and vulcanization accelerators.

芳香亚甲胺是通过将苯胺与甲醛反应,然后通过蒸馏去除大部分水分来制备的,在蒸馏过程中,一定量的低沸点醇存在,如果需要,也可以在反应过程中或其中的一部分存在。通过这种新颖工艺获得的芳香亚甲胺是制备除草剂、特别是苗前除草剂和苗后除草剂、杀菌剂、杀虫剂、抑菌剂、抗真菌剂和硫化加速剂的宝贵起始材料。
